Huo Sining could understand a bit of this. Since she acquired the Water-Repelling Pearl, she has been particularly concerned about the ocean and has read many materials. Therefore, she understood why Bai Yishan said it wasn't easy to find a deep-sea salvage company.
Human deep-sea salvage must overcome not just the darkness of the deep water but also immense pressure from the depths.
Because there is a limit to the water pressure that humans can tolerate while diving, deep-sea salvage must have the most advanced salvage ships and precise high-end underwater operational robots.
Currently, domestic naval military salvage ships can dive to a depth of about 450 meters, while civilian salvage companies' operational depth definitely doesn't exceed 200 meters. Below that, you might as well pray without any hope of a response.
Therefore, Huo Sining estimated that Bai Guoming was probably wasting his efforts looking for an ocean salvage company everywhere.
